Ingredients

Scale
  • 1 box white cake mix (about 15.25 oz or 432 g) – Duncan Hines recommended
  • 3 large eggs, room temperature
  • 1 cup whole milk (240 ml) or almond milk for dairy-free option
  • 1/3 cup vegetable oil (80 ml)
  • 1 teaspoon vanilla extract
  • 2 cups heavy whipping cream (480 ml), chilled
  • 1/4 cup granulated sugar (50 g)
  • 1 teaspoon vanilla extract
  • 1 cup fresh blueberries (about 150 g)
  • 1 1/2 cups fresh strawberries (about 225 g), hulled and sliced
  • Optional: 1/4 cup raspberries or blackberries for extra color contrast

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13 inch (23×33 cm) baking pan with butter or non-stick spray and lightly dust with flour.
  2. In a large bowl, combine the white cake mix, 3 large eggs, 1 cup whole milk, 1/3 cup vegetable oil, and 1 teaspoon vanilla extract. Beat on medium speed for about 2 minutes until smooth and well combined.
  3. Pour the batter evenly into the prepared pan. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
  4. Allow the cake to cool in the pan on a cooling rack for at least 30 minutes.
  5. In a chilled mixing bowl, combine 2 cups heavy whipping cream, 1/4 cup granulated sugar, and 1 teaspoon vanilla extract. Whip on medium-high speed until soft peaks form (3-5 minutes).
  6. Once the cake is fully cooled, spread the whipped cream evenly over the top with a spatula.
  7. Arrange fresh blueberries in the top left corner to form the blue field of the flag. Arrange sliced strawberries in horizontal rows across the remaining space to mimic the red stripes, leaving white space from the whipped cream to represent the white stripes. Optionally add raspberries or blackberries for extra color.
  8. Refrigerate the cake for at least 1 hour before serving to help the whipped cream set and flavors meld.
  9. For clean slices, run a sharp knife under hot water, dry it, and then slice the cake.

Notes

Do not rush cooling the cake before frosting to prevent whipped cream from melting. Whip cream until soft peaks form to avoid grainy texture or butter formation. Use fresh, firm berries to prevent sogginess. For clean slices, warm the knife before cutting. Store leftovers covered in the fridge for up to 2 days. For dairy-free, use almond milk and coconut whipped cream. Gluten-free cake mix can be used for gluten-free version.
